    [FLINK-5091] Formalize the Mesos AppMaster environment for docker 
compatibility

    Fixes FLINK-5091 and FLINK-4826.
    
    - introduced ContainerSpecification.
    - reworked how the TM container environment is constructed; eliminated
    special-case environment variables, file layout.
    - added dynamic configuration support to GlobalConfiguration.
    - integrated the SecurityContext into AM/TM runners.
    - added config setting for Mesos framework user.
    - support DCOS side-channel authentication.
    - set the FS default scheme.
    - made the artifact server more generic (no assumption about existence
    of dispatcher, Path-based).
    - moved some test code related to overriding the JVM’s env.

    [FLINK-4921] Upgrade to Mesos 1.0.1
    
    Updated the Mesos dependency, to unlock some new features (notably the
    ability to fetch into sandbox sub-directories).
    
    Shaded the protobuf dependency because the new Mesos library depends on
    a newer version than does akka-remoting.

>
> For scenarios where the AppMaster is launched from a docker image, it would 
> be ideal to use the installed Flink rather than rely on a special file layout 
> in the sandbox directory.
> This is related to DCOS integration, which (in 1.2) will launch the AppMaster 
> via Marathon (as a top-level DCOS service).  The existing code assumed that 
> only the dispatcher (coming in 1.3) would launch the AppMaster.
